It was the year’s second-largest attended single-day sporting event in the state of Texas, trailing only April’s Samsung Mobile 500 at Texas Motor Speedway.

TMS officials said Sunday’s one-day attendance figure is nearly the size of the three sold-out World Series games that were played at Rangers Ballpark in Arlington or almost two seated capacity crowds for a Dallas Cowboys NFL game at Cowboys Stadium.

Officials were also pleased at Sunday’s crowd considering the fact that the Cowboys played earlier in the day and drew 81,510 fans in their game against the Seattle Seahawks.

An estimated crowd of 151,000 fans watch David Ragan, driver of the #6 UPS My Choice Ford and Greg Biffle, driver of the #16 3M Scotch-Blue Painter's Tape Ford, lead the field at the start of the NASCAR Sprint Cup Series AAA Texas 500 at Texas Motor Speedway on November 6, 2011 in Fort Worth, Texas.
